1 Claim.

The present invention relates to improvements in alloys, and is moreparticularly concerned with the production of a stainless alloy havingexceptional resistance to corrosion from any medium with which it may bebrought into contact.

The alloy lends itself admirably to various methods of handling, andwhen cast or otherwise formed may be given a smooth, lustrous finishwith a mirror-like surface. The tensile strength is adequate for normalpurposes, and by varying certain of the constituents it may be madeexceedingly hard if so desired. However, its principal use is inconnection with utensils and implements of a widely varied character,where its inherent protection against corrosion, stains and the likemake it of particular utility.

I have found in actual practice that an alloy having the followingconstituents within the given proportions is admirably adapted for theThe elements as indicated in the table are capable of completelycombining into a homogeneous, tough alloy which may be cast, machinedand polished to produce a high lustrous finish which cannot be stainedor marred by any known materials with which the article is likely tocome in contact.

Although not limited to this class of article, I may point out that thealloy is particularly suited for cooking utensils, due to the brilliantand lasting finish which may be given it, and its freedom from stainswhich otherwise occur in use. The alloy has excellent heat conductingproperties, and is not frangible or breakable in use.

What is claimed is:

A stainless alloy suitable for casting and consisting of nickel tochromium 10 to 30%, steel not exceeding 12%, tungsten .3 to 4%, and

cobalt .2 to 2%.
